The Official Portal to Your Decentralized Future
In 2026, the internet is more than just data—it is value. The Coinbase Extension®™ serves as your digital passport to this new economy. While the traditional Coinbase exchange provides a world-class platform for buying and selling, the Coinbase Wallet Extension is designed for those who want to go further.
It is a self-custody bridge that allows you to interact with decentralized applications (dApps), manage complex NFT portfolios across multiple chains, and participate in the governance of the protocols you love. With the integration of the "Base" network and advanced Layer 2 solutions, the extension has become the fastest and most cost-effective way to stay onchain.
Add the extension to your Chrome or Brave browser via the official web store. Always verify the developer is Coinbase Inc.
Generate a new 12-word recovery phrase or import an existing wallet from MetaMask or Trust Wallet using your seed phrase.
Write down your Recovery Phrase on paper. In 2026, digital screenshots are the #1 cause of theft. Keep it offline and hidden.
Optionally connect your Coinbase.com account to instantly transfer funds to your self-custody extension with one click.
Register your unique "cb.id" username to replace long, complex wallet addresses with a simple, readable name.
Unlike other browser wallets, the Coinbase Extension offers Smart Transaction Previews. This feature analyzes smart contracts in real-time before you sign, warning you if a transaction is likely to drain your assets or if the contract has been flagged as a scam by the community.
Move assets between Ethereum, Base, Polygon, and Solana without leaving the extension. The built-in aggregator finds the best price across dozens of liquidity providers, ensuring you never overpay for a swap.
Manage your digital collectibles with ease. The 2026 update includes native support for "Dynamic NFTs" and automated floor-price alerts, so you always know the value of your vault.
For maximum security, the Coinbase Extension allows you to link your Ledger or Trezor device. This means your private keys stay on your physical hardware, while you enjoy the sleek interface of the Coinbase UI.
No. Your Coinbase.com account is "custodial," meaning Coinbase holds the keys for you. The Coinbase Extension®™ is "self-custody," meaning YOU hold the keys. If you lose your recovery phrase for the extension, Coinbase cannot help you reset it.
Yes. By utilizing the "Pay" feature within the extension, you can scan QR codes at participating merchants or send crypto to any cb.id, ENS, or Lens handle instantly.
On specific networks like Base, the Coinbase Extension supports "Account Abstraction," allowing certain dApps to sponsor your transaction fees, meaning you can trade without holding the native gas token (like ETH).
Don't panic. Transactions are recorded on the blockchain, not your browser. Once you restart, check your transaction history. If the transaction wasn't "confirmed," your funds never left your wallet.
The extension is for desktop browsers. For mobile, download the **Coinbase Wallet App** on iOS or Android. You can sync both using your 12-word recovery phrase to manage the same wallet on the go.
As we navigate the decentralized web, the most important thing to remember is that you are your own bank. The Coinbase Extension gives you incredible power, but with that comes the responsibility of protecting your seed phrase.
Avoid clicking on "sponsored" links in search engines, never share your screen with "support" agents, and always double-check the URL of the dApps you are connecting to. With the right habits, the Coinbase Extension is the safest and most powerful tool in your financial arsenal.
